misc: st_core: Error triggered by convert "char" to "int"
When st driver decodes protocol index received from raw data,
it does a value convert from "char" to "int". Because it's sign
extension from bit8 to bit32, the "int" value maybe minus, in
another word, the protocol index might be minus, but driver doesn't
filter such case and may continue access memory pointed by this
minus index.
This patch is to change the variable type of index from "int"
to "unsigned char", so that it avoids do such kind of type
conversion.

drivers/w1/masters/mxc_w1.c: use devm_ functions
The various devm_ functions allocate memory that is released when a driver
detaches. This patch uses these functions for data that is allocated in
the probe function of a platform device and is only freed in the remove
function.
At the same time, this fixes two faults. First, mdev, the result of
kzalloc, was never freed. Second, on failure of ioremap, 0 was returned.
This has been replaced by -EBUSY, which was the failure value for the call
to request_mem_region, with which the call to ioremap has been combined.
The warning message on failure of ioremap is dropped, because
devm_request_and_ioremap already gives such messages on failure.
Finally, the initial call to platform_get_resource is moved closer to the
call to devm_request_and_ioremap, which takes care of checking whether its
result is NULL, implying that a test on the result of this call to
platform_get_resource is not needed.

Noticed while reviewing the fence locking in the radeon pageflip

v2: Instead of grabbing the bdev->fence_lock in object_transfer just

ARM: highbank: fix secondary boot and hotplug
With commit 384a290 (ARM: gic: use a private mapping for CPU target
interfaces), wake-up IPIs now go to all cores as the gic cpu interface
numbering may not follow core numbering. This broke secondary boot on
highbank since the boot address was already set for all secondary cores,
this caused all cores to boot before the kernel was ready.
Fix this by moving the setting of the jump address to
highbank_boot_secondary instead of highbank_smp_prepare_cpus and
highbank_cpu_die. Also, clear the address when we boot. This prevents
cores from booting before they are actually triggered and is also necessary
to get suspend/resume to work.

drm/prime: drop reference on imported dma-buf come from gem
Increasing ref counts of both dma-buf and gem for imported dma-buf come from gem
makes memory leak. release function of dma-buf cannot be called because f_count

because of exported dma-buf.
So I add dma_buf_put() for imported gem come from its own gem into each drivers

Summary:
- change exynos file license
. Most of exynos files had been copied from some randome
file and not updated correctly(wrong company name used).
This was our mistakes so chagnes it correctly. For this,
I'm not sure that this patch should go to -fix or -next.
So please give me any comment if there is any problem.
- consider buffer allocation without iommu
. Without iommu, dma_alloc_attrs function allocates some
memory region and returns cpu address so this patch makes
the cpu address to be set to buf->kvaddr correctly
- cleanups to ipp relevant codes.
- use common finish page flip function
. to avoid the duplication of same code, use
exynos_drm_crtc_finish_pageflip function commonly instead
of each one.
- fix fimd resume issue.
. when fimd was turned off by suspend, there was one issue that
the fimd wasn't turned on by resume so fix it chaing resume
condition.
